In-situ Road cold recycler construction technology of expres

The pavement Road cold recycler machine is an environmentally-friendly and efficient road construction equipment designed and manufactured to adapt to the construction of urban and rural roads. During the operation, the old asphalt pavement is milled and broken while adding stabilizers (cement, lime, water, etc.) On-site mixing forms a new road base through shaping and compaction.

The in-situ Road cold recycler construction process is as follows:

1. Investigate the structural condition of the old road and pave the test road to determine the process parameters such as the depth to be regenerated and the amount of new aggregate added. The length should not be less than 200 meters.

2. Before the Road cold recycler construction, the old road surface should be cleaned, and the obvious subsidence and pits of the old road should be filled.

3. Manual or mechanical paving additives (cement, lime, new aggregate, etc.), calculated according to the designed addition amount per square meter.

4. Cold regenerator works. During the construction process, the depth and speed should be checked at any time to ensure that the regeneration depth and the broken gradation of the mixture are reasonable.

5. Use the bulldozer to level up at first, and evenly discharge the pressure, then use the grader to scrape to the design elevation.

6. Detect the water content, replenish water if necessary to make it meet the optimal water content, and then roll the road to form a new road base.

7, road health. The health period is not less than 7 days, and traffic control is performed during the health period.

8. Paving surface course, compacting to form new pavement.

Cement pavement crusher has 6 advantages compared to traditional construction methods

(1) Low cost

(2) Increase the level of the old road

(3) Does not damage the roadbed

(4) Can not interrupt traffic

(5) Short construction period

(6) Protect the environment and resources [Failure of the concrete mixer synchronizer]
